[0007] The disadvantage of the existing structure 2 is: when the upper, lower and lateral slight relative displacements of the axle box relative to the frame are realized through the elastic deformation of the rubber, the lateral force is provided by the interference fit connection between the elastic sleeve of the mandrel and the inner hole of the tie rod, and the lateral force When the force is large, it will produce lateral movement, causing safety hazards (see Figure 2A to Figure 3 )

Embodiment Construction
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0038] As shown in the figure, the present invention proposes a method for preventing lateral movement of axle box tie rods for locomotive bogies and an axial tie rod using the method. The axle box tie rods include tie rod body 1, mandrel 2, mandrel elastic sleeve 3. Two mandrels 2 are assembled in the hole 11 of the tie rod body 1, and the mandrel elastic sleeve 3 is vulcanized on the two mandrels 2. The outside of the mandrel elastic sleeve 3 is a metal sleeve, an...

The invention discloses a method for preventing an axle box link of a locomotive bogie from moving laterally and an axle box link. The axle box link comprises two spindles, a link body and spindle elastic sleeves, the two ends of the link body are respectively provided with a hole, the two spindles are respectively assembled in the two holes and respectively vulcanized with the spindle elastic sleeves, a metal sleeve is arranged outside each spindle elastic sleeve, and the spindle elastic sleeves are matched with the link body through the metal sleeves so that the two spindles are elastically connected through the link body, wherein an elastic stop structure is arranged between the spindle elastic sleeves and the link body to prevent the axle box link of the locomotive bogie from moving laterally, and moreover, by using the rubber elastic deformation of the elastic stop structure, an axle box can slightly and relatively displace up, down and laterally relative to a framework.
Description
technical field [0001] The invention relates to an axle box tie rod for a locomotive bogie, in particular to a method and a structure for preventing lateral movement of the inner mandrel of the axle box tie rod by adopting a transverse stop structure. Background technique [0002] The axle box tie rod of the locomotive bogie is the elastically connected part of the locomotive wheel set and the frame, which transmits the traction force, braking force, lateral force, etc. Slight relative displacement of up, down and lateral. [0003] In the prior art, two structures are mainly used to realize the elastic connection between the locomotive wheel set and the frame: [0004] Existing structure one is mainly made up of mandrel 81, snap ring 82, end cap 83, pull rod 84, mandrel elastic sleeve 85, end cap elastic pad 86 (see Figure 1A , Figure 1B ). There are mandrel holes for installing the mandrel 81 at both ends of the pull rod 84. There is a mandrel elastic sleeve 85 between...
